There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Heap-based buffer overflow in the xwd_decode_frame function in libavcodec/xwddec.c in FFmpeg before
    2.8.12, 3.0.x before 3.0.8, 3.1.x before 3.1.8, 3.2.x before 3.2.5, and 3.3.x before 3.3.1 allows remote
    attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a
    crafted file. (CVE-2017-9991)

  - Heap-based buffer overflow in the decode_dds1 function in libavcodec/dfa.c in FFmpeg before 2.8.12, 3.0.x
    before 3.0.8, 3.1.x before 3.1.8, 3.2.x before 3.2.5, and 3.3.x before 3.3.1 allows remote attackers to
    cause a denial of service (application crash) or possibly have unspecified other impact via a crafted
    file. (CVE-2017-9992)

  - libavcodec/webp.c in FFmpeg before 2.8.12, 3.0.x before 3.0.8, 3.1.x before 3.1.8, 3.2.x before 3.2.5, and
    3.3.x before 3.3.1 does not ensure that pix_fmt is set, which allows remote attackers to cause a denial of
    service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a
    crafted file, related to the vp8_decode_mb_row_no_filter and pred8x8_128_dc_8_c functions. (CVE-2017-9994)

  - The cdxl_decode_frame function in libavcodec/cdxl.c in FFmpeg 2.8.x before 2.8.12, 3.0.x before 3.0.8,
    3.1.x before 3.1.8, 3.2.x before 3.2.5, and 3.3.x before 3.3.1 does not exclude the CHUNKY format, which
    allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or
    possibly have unspecified other impact via a crafted file. (CVE-2017-9996)

Several security vulnerabilities were corrected in the libav multimedia library which may lead to a denial of service, information disclosure or the execution of arbitrary code if a malformed file is processed.

CVE-2017-9993

Libav does not properly restrict HTTP Live Streaming filename extensions and demuxer names, which allows attackers to read arbitrary files via crafted playlist data.

CVE-2017-9994

libavcodec/webp.c in Libav does not ensure that pix_fmt is set, which allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file, related to the vp8_decode_mb_row_no_filter and pred8x8_128_dc_8_c functions.

CVE-2017-14055

denial of service in mv_read_header() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption.

CVE-2017-14056

denial of service in rl2_read_header() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption.

CVE-2017-14057

denial of service in asf_read_marker() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption.

CVE-2017-14170

denial of service in mxf_read_index_entry_array() due to lack of an EOF (End of File) check might cause huge CPU consumption.

CVE-2017-14171

denial of service in nsv_parse_NSVf_header() due to lack of an EOF (End of File) check might cause huge CPU consumption.

CVE-2017-14767

The sdp_parse_fmtp_config_h264 function in libavformat/rtpdec_h264.c mishandles empty sprop-parameter-sets values, which allows remote attackers to cause a denial of service (heap buffer overflow) or possibly have unspecified other impact via a crafted sdp file.

CVE-2017-15672

The read_header function in libavcodec/ffv1dec.c allows remote attackers to have unspecified impact via a crafted MP4 file, which triggers an out-of-bounds read.

CVE-2017-17130

The ff_free_picture_tables function in libavcodec/mpegpicture.c allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file, related to vc1_decode_i_blocks_adv.

CVE-2018-6621

The decode_frame function in libavcodec/utvideodec.c in Libav allows remote attackers to cause a denial of service (out of array read) via a crafted AVI file.

CVE-2018-7557

The decode_init function in libavcodec/utvideodec.c in Libav allows remote attackers to cause a denial of service (Out of array read) via an AVI file with crafted dimensions within chroma subsampling data.

CVE-2018-14394

libavformat/movenc.c in Libav allows attackers to cause a denial of service (application crash caused by a divide-by-zero error) with a user crafted Waveform audio file.

CVE-2018-1999010

Libav contains multiple out of array access vulnerabilities in the mms protocol that can result in attackers accessing out of bound data.

For Debian 8 'Jessie', these problems have been fixed in version 6:11.12-1~deb8u4.

We recommend that you upgrade your libav packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - libavcodec/webp.c in FFmpeg before 2.8.12, 3.0.x before 3.0.8, 3.1.x before 3.1.8, 3.2.x before 3.2.5, and     3.3.x before 3.3.1 does not ensure that pix_fmt is set, which allows remote attackers to cause a denial of     service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a     crafted file, related to the vp8_decode_mb_row_no_filter and pred8x8_128_dc_8_c functions. (CVE-2017-9994)

Note that Nessus relies on the presence of the package as reported by the vendor.
